OIL-CUP.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed August 13, 1917. SerialNo. 185,956.

To all whom it may concern:

Be it known that I, WILLIAM D. HUGHES, a citizen of the United States, residing at Oondon, in the county of Gilliam and State of Oregon, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification.

My invention relates to new and useful improvements in lubricators and more particularly to an oil cup. 1

The primary ob'ect of the invention is the provision of an oil cup having an adjustable cap and means for holding the cap in its adjusted position.

A further object is the provision of a spring catch connected to the cap for holdingit in its adjusted position.

Another object is the construction of the catch in such a manner that it may be disconnected from the cap for adjustment.

Still another object of the invention is the construction of a spring catch from a single strip of material.

With these and other objects in view, the invention consists in the novel details of construction and arrangement of parts which will he more clearly understood from the following description and drawing, in which,

Figure 1 is a side elevation,

Fig. 2 is a longitudinal vertical section,

Fig. 3 is a front view,

Fig. 4 is a fragmental cross section showing the groove in the body of the cup, and

Fig. 5 is a perspective of a slightly modified form of spring catch.

In carrying out my invention, the body portion of my oil cup comprises a circular vertical wall 1 having a vertical inclined groove 2 therein, a funnel-shaped extension 3 and an exteriorly threaded nipple 4c. The vertical wall portion 1 is exterio-rly threaded and by reference to the drawing, more particularly to Fig. 2, it will be seen that the vertical groove 2' terminates a short distance from the top of the wall whereby several of the threads at the top of the wall will be uninterrupted, whereas the other threads will be interrupted at the groove.

A-cap is indicated at 5 and is interiorly threaded, said threads engaging the exterior threads on the wall 1, whereby the cap may be adjusted in respect to the body. Ears 6 having openings therein are formed on the exterior of the cap 5, or secured thereto in any suitable manner, and a pin 7 extends through the openings in the ears 6 and is held in position by means of a cotter pin, 1

indicated at 8. A notch 9 is formed in the lower edge of the cap, for the purpose as will be presently described.

A spring catch is carried by the cap 5 and is adapted to engage the vertical groove 2 in the body of the cup. This spring catch is made from a single strip of wire bent to form the vertical portion indicated at 10 having the right angled extension 11 passing through the notch 9 and the downwardly extending portion 12, formed on the right angled extension 11 which is adapted to be received in the groove 2 and extend longitudinally thereof. The upper end of the wire is bent to form a coil 13 through which the pin 7 is adapted to pass for connecting the catch to the cap. The end 14: of the catch is adapted to engage the upper edge of the cap, as is more particularly illustrated in Fig. 2 of the drawings. The extension 12 on the lower end of the catch is of such a length as to extend beneath the lower edge of the cap so thatone can always see if'the catch is properly engaged in the groove 2.

In Fig. 5 of the drawings I have illustrated a slightly modified form of catch which is formed from a single strip of wire bent to form the parallel extending strips 15 and 16 which are twisted together at 17. The strip 15 is bent so as to form a right angled projection 18 which is adapted to pass through the notch 9 in the bottom edge of the cap and engage in the groove 2. The upper ends of the strips 15 and 16 are bent to form the coil 19 having the two extending end portions 20 which are adapted to engage the upper edge of the cap. This modified form of catch is adapted to be used more particularly on the larger forms of oil cups where greater tension is desired. In this form of the invention it will be understood that the pin 7 will pass through the coil 19 for connecting the catch to the cap.

Having fully describedthe detailed construction of my oil cup, it is thought that the advantages and mode of operation will be clearly understood. It will be seen that I have provided an oil cup which is simple and inexpensive in construction and one which is particularly adapted for what is known as hard grease although any kind of lubricant can be used. The oil cup is also adapted for use in many places and when in use the threaded nipple 4 will be screwed into the opening of the parts to be lubricated. The lubricant will be placed in the bodyportion of the cup and the cap screwed thereon. By having the uninterrupted threads at the top of the vertical wall, it will be seen that the cap may be given an initial start whereby the parts will be connected. When the cap is screwed down a sufiicient distance the extension 12 will engage in the groove 2. By having the groove inclined, as more particularly illustrated in Fig. 1 of the drawings, it will be noted that the cap may be screwed on to the body but the shoulder, engaged by the extension 12, will prevent the cap from unscrewing. When it is desired to remove the cap the vertical portion 10 may be engaged by the fingers and the extension 12 removed from the groove and drawn through the notch 9. It will be noted that I have provided a catch which is detachable from the cap by removing the pin 7 and when removed the catch may be adjusted, by bending the ends thereof, so as to put the coil 13 under a greater or lesser tension. It will also be seen that the catch is constructed of a single piece of material bent to form an eye whereby it is connected to the cap as well as an extension entering a groove in the body. In the modified form of the invention as illus trated in Fig. 4 of the drawings the operation will be the same, and, as previously de scribed, the projection 18 will pass through the notch 9 and be received in the groove.

Copies 01 this patent may be obtained for This modified form of catch, is as above described, particularly adapted Where a catch of greater strength or tension is required.

Having fully described my invention what I claim as new and desire for Letters Patent is In an oil cup, an exteriorly threaded body, said body being provided with a vertically extending groove in its outer circumferential face, an interior threaded cover screwed on the said body, said cover being provided with an opening adapted to be brought into alinement with said groove, the cover being further provided adjacent its upper end with two spaced outwardly projecting cars, a spring catch formed from a single length of resilient wire bent to provide a locking element adapted to project through the opening of the cover into the groove of said body so as to lock the cover against reverse rotation, the catch being further bent to provide a coil adjacent its upper end and an element projecting beyond said coil, said coil being adapted to receive a securing pin and the upwardly projecting element being adapted to engage the cover adjacent the upper end thereof and a cotter pin inserted through said securing pin.

In testnnony whereoi' I affix my signature in presence of two witnesses.

WILLIAM D. HUGHES.
